20 | /* To use the dynarray facility, you need to include | ||
21 | <malloc/dynarray-skeleton.c> and define the parameter macros | ||
22 | documented in that file. | ||
23 | |||
24 | A minimal example which provides a growing list of integers can be | ||
25 | defined like this: | ||
26 | |||
27 | struct int_array | ||
28 | { | ||
29 | // Pointer to result array followed by its length, | ||
30 | // as required by DYNARRAY_FINAL_TYPE. | ||
31 | int *array; | ||
32 | size_t length; | ||
33 | }; | ||
34 | |||
35 | #define DYNARRAY_STRUCT dynarray_int | ||
36 | #define DYNARRAY_ELEMENT int | ||
37 | #define DYNARRAY_PREFIX dynarray_int_ | ||
38 | #define DYNARRAY_FINAL_TYPE struct int_array | ||
39 | #include <malloc/dynarray-skeleton.c> | ||
40 | |||
41 | To create a three-element array with elements 1, 2, 3, use this | ||
42 | code: | ||
43 | |||
44 | struct dynarray_int dyn; | ||
45 | dynarray_int_init (&dyn); | ||
46 | for (int i = 1; i <= 3; ++i) | ||
47 | { | ||
48 | int *place = dynarray_int_emplace (&dyn); | ||
49 | assert (place != NULL); | ||
50 | *place = i; | ||
51 | } | ||
52 | struct int_array result; | ||
53 | bool ok = dynarray_int_finalize (&dyn, &result); | ||
54 | assert (ok); | ||
55 | assert (result.length == 3); | ||
56 | assert (result.array[0] == 1); | ||
57 | assert (result.array[1] == 2); | ||
58 | assert (result.array[2] == 3); | ||
59 | free (result.array); | ||
60 | |||
61 | If the elements contain resources which must be freed, define | ||
62 | DYNARRAY_ELEMENT_FREE appropriately, like this: | ||
63 | |||
64 | struct str_array | ||
65 | { | ||
66 | char **array; | ||
67 | size_t length; | ||
68 | }; | ||
69 | |||
70 | #define DYNARRAY_STRUCT dynarray_str | ||
71 | #define DYNARRAY_ELEMENT char * | ||
72 | #define DYNARRAY_ELEMENT_FREE(ptr) free (*ptr) | ||
73 | #define DYNARRAY_PREFIX dynarray_str_ | ||
74 | #define DYNARRAY_FINAL_TYPE struct str_array | ||
75 | #include <malloc/dynarray-skeleton.c> | ||
76 | |||
77 | Compared to scratch buffers, dynamic arrays have the following | ||
78 | features: | ||
79 | |||
80 | - They have an element type, and are not just an untyped buffer of | ||
81 | bytes. | ||
82 | |||
83 | - When growing, previously stored elements are preserved. (It is | ||
84 | expected that scratch_buffer_grow_preserve and | ||
85 | scratch_buffer_set_array_size eventually go away because all | ||
86 | current users are moved to dynamic arrays.) | ||
87 | |||
88 | - Scratch buffers have a more aggressive growth policy because | ||
89 | growing them typically means a retry of an operation (across an | ||
90 | NSS service module boundary), which is expensive. | ||
91 | |||
92 | - For the same reason, scratch buffers have a much larger initial | ||
93 | stack allocation. */ | ||
